MIAMI, Fla. (MarketWatch) — If you are going to day trade, it’s essential to have a set of rules to manage any possible scenario. Even more important, you must also have the discipline to follow these rules.

Sometimes, in the heat of battle, traders will throw out their own rules and play it by ear — usually with disastrous results.

Although there are many rules, the following are the 10 most important:

1. The three E’s: enter, exit, escape

Rule No. 1 is having an enter price, an exit price, and an escape price in case of a worst-case scenario. This is rule number one for a reason. Before you press the “Enter” key, you must know when to get in, when to get out, and what to do if the trade doesn’t work out as expected.

Escaping a trade, also known as using a stop price, is essential if you want to minimize losses. Knowing when to get in or out will help you to lock in profits, as well as save you from potential disasters. Read more: 4 big risks to your investment portfolio now.

2. Avoid trading during the first 15 minutes of the market open

Those first 15 minutes of market action are often panic trades or market orders placed the night before. Novice day traders should avoid this time period while also looking for reversals. If you’re looking to make quick profits, it’s best to wait a while until you’re able to spot rewarding opportunities. Even many pros avoid the market open.

3. Use limit orders, not market orders

A market order simply tells your broker to buy or sell at the best available price. Unfortunately, best doesn’t necessarily mean profitable. The drawback to market orders was revealed during the May 2010 “flash crash.” When market orders were triggered on that day, many sell orders were filled at 10-, 15-, or 20 points lower than anticipated. A limit order, however, lets you control the maximum price you’ll pay or the minimum price you’ll sell. You set the parameters, which is why limit orders are recommended.

4. Rookie traders should avoid using margin

When you use margin, you are borrowing money from your brokerage to finance all or part of a trade. Full-time day traders (i.e. pattern day traders) are usually allowed 4:1 intraday margin. For example, with a $30,000 trading account, you’ll be given enough buying power to purchase $120,000 worth of securities. Overnight, however, the margin requirement is still 2:1.

When used properly, margin can leverage, or increase, potential returns. The problem is that if a trade goes against you, margin will increase losses. One of the reasons that day trading got a bad name a decade ago was because of margin, when people cashed in their 401k(s) and borrowed bundles of money to finance their trades. When the bull market ended in 2000, so did many traders’ accounts. Bottom line: if you are a novice trader, first learn how to day trade stocks without using margin.

5. Have a selling plan

Many rookies spend most of their time thinking about stocks they want to buy without considering when to sell. Before you enter the market, you need to know in advance when to exit, hopefully with a profit. “Playing it by ear” is not a selling strategy, nor is hope. As a day trader, you’ll set a price target as well as a time target.
